Description

Technical Field

[0001] The utility model belongs to the technical field of concrete construction, in particular to a cooling device for concrete construction. Background Art

[0002] In the field of concrete construction, especially when it comes to large-volume concrete structures, it is crucial to control and reduce the temperature of concrete. Large-volume concrete will generate a lot of heat during the curing process. If this heat cannot be effectively removed, it will cause the temperature inside the concrete to rise, causing uneven early strength development of the concrete, cracks, and even damage to the concrete structure. In addition, high temperature will also affect the durability and service life of concrete. Therefore, how to effectively cool large-volume concrete has become an important topic in concrete construction technology.

[0003] Traditional cooling methods include using cooling water circulation, setting up cooling pipes or using external cooling equipment, but these methods often have problems such as low efficiency, high cost, complex operation or certain impact on the environment. For example, the use of cooling water circulation requires a large amount of water resources, and the cooling effect is affected by many factors; setting up cooling pipes requires complex pre-embedding work before concrete pouring, which increases the difficulty of construction; and although external cooling equipment can provide a relatively stable cooling effect, the equipment cost is high and the site requirements are high, which limits its wide application.

[0004] Therefore, the development of a new type of cooling device for concrete construction aims to solve the temperature control problem of large-volume concrete in a more efficient, economical and environmentally friendly way, which has important engineering application value and market demand. Utility Model Content

[0005] The purpose of the utility model is to provide a cooling device for concrete construction, which, through the combination of a main cooling pipeline, a drainage duct, a branch drainage pipe, etc., can not only effectively reduce the temperature of large-volume concrete and increase the strength and stability of the structure, but also has good adaptability and flexibility, and can meet the cooling needs in different construction environments.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a cooling device for concrete construction, comprising a main cooling pipe placed inside the concrete; two ends of the main cooling pipe are respectively fixedly connected with a drainage conduit, and the free end of the drainage conduit is placed outside the concrete; a plurality of first heat-conducting rods arranged perpendicular to the axial direction of the main cooling pipe are fixed on the outer wall of the main cooling pipe; a row of first water-stop plates evenly distributed along the axial direction of the drainage conduit are fixed on the outer wall of the drainage conduit; and a first internal thread is arranged on the inner wall of the end of the drainage conduit.

[0008] As a preferred technical solution of the utility model, a first rectangular plate is fixed to the outer wall of the end of the drainage duct; the distance between the first rectangular plate and the end face of the drainage duct is no more than 18 mm; four first steel bar heads are fixed to the side of the first rectangular plate away from the end face of the drainage duct; and a first bolt is threadedly connected to the end of the drainage duct.

[0009] As a preferred technical solution of the utility model, a water pipe joint is installed at the end of the drainage catheter.

[0010] As a preferred technical solution of the utility model, the outer wall of the main cooling pipe is fixedly connected to a plurality of branch drainage pipes; a row of second water stop plates evenly distributed along the axial direction are fixed to the outer wall of the branch drainage pipe; a second rectangular plate is fixed to the outer wall of the end of the branch drainage pipe; four second steel bar heads are fixed to the side of the second rectangular plate away from the end face of the branch drainage pipe; the distance between the second rectangular plate and the end face of the branch drainage pipe is not more than 18 mm; and a second internal thread is provided on the inner wall of the end of the branch drainage pipe.

[0011] As a preferred technical solution of the utility model, the end of the branch drainage tube is threadedly connected with a second bolt.

[0012] As a preferred technical solution of the utility model, a plurality of second heat-conducting rods which are arranged perpendicular to the axial direction of the drainage conduit are fixed to the outer wall of the drainage conduit.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model can effectively conduct the heat inside the concrete to the cooling pipe by arranging a main cooling pipe and a drainage pipe inside the concrete, and fixing a first heat-conducting rod on the outer wall of the main cooling pipe, and take away the heat through the water flow, thereby quickly reducing the temperature of the concrete center and the surrounding area.

[0015] 2. After completing the cooling function, the main cooling pipe and drainage duct of the utility model will be filled with cement slurry and combined with concrete. This will not only not weaken the structure of the concrete, but will increase the internal support of the concrete due to the presence of the pipe, thereby improving the strength and stability of the overall structure.

[0016] 3. The first water stop plate design on the outer wall of the drainage duct of the utility model effectively prevents the flow of water along the outer wall of the drainage duct during the solidification process of concrete, reduces possible water leakage problems, and maintains the overall dryness and stability of the concrete.

[0017] 4. The utility model adopts the design of the first rectangular plate fixed on the outer wall of the end of the drainage duct, so that the cooling device can be easily installed and positioned before pouring concrete, and it is also convenient to adjust according to the actual thickness of the template used.

[0018] 5. The utility model installs branch drainage pipes on the main cooling pipe, and can connect water pipe joints and water supply pipes at the ends of each branch drainage pipe, so that the cooling system can be flexibly configured according to actual cooling needs, thereby enhancing the applicability and cooling effect of the system.

[0019] 6.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:

[0031] See also Figure 1-2 and Figure 4 As shown, the utility model is a cooling device for concrete construction, including a main cooling pipe 1 placed inside the concrete. A drainage duct 2 is fixedly connected to both ends of the main cooling pipe 1, and the free end of the drainage duct 2 is placed outside the concrete. A plurality of first heat-conducting rods 3 arranged perpendicular to the axial direction of the main cooling pipe 1 are fixed to the outer wall. A row of first water stop plates 4 uniformly arranged along the axial direction are fixed to the outer wall of the drainage duct 2. A first internal thread 5 is provided on the inner wall of the end of the drainage duct 2. The first water stop plate 4 plays a role in preventing stagnant water from flowing along the outer wall of the drainage duct 2 during the solidification process of concrete, that is, after solidification.

[0032] Among them, a first rectangular plate 6 is fixed to the outer wall of the end of the drainage duct 2. The thickness range of conventional templates is 12mm-18mm. For this reason, the distance between the first rectangular plate 6 and the end face of the drainage duct 2 is set to be no more than 18mm. In actual use, the first rectangular plate 6 is welded according to the thickness of the template used. Four first steel bar heads 7 are fixed to the side of the first rectangular plate 6 away from the end face of the drainage duct 2. The end of the drainage duct 2 is threadedly connected with a first bolt 15. During the process of manufacturing the template, the first rectangular plate 6 is attached to the template, and a through hole matching the end of the drainage duct 2 is provided on the template. When the first bolt 15 is connected to the first internal thread 5 at the end of the drainage duct 2, the first rectangular plate 6 at the end of the drainage duct 2 is tightly attached to the template, so as to realize the installation and positioning of the entire cooling device before pouring concrete.

[0033] After pouring, the main cooling pipe 1 is vertically fixed in the center of the large volume concrete, and the main parts of the two drainage ducts 2 are buried in the large volume concrete, leaving only the ends of the drainage ducts 2. After demolding, a water pipe joint 8 is installed at the ends of the drainage ducts 2. The lower water pipe joint 8 is connected to the water inlet pipe, and the lower water pipe joint 8 is connected to the drain pipe. Cold water enters the main cooling pipe 1 in the center of the large volume concrete from the lower drainage duct 2, and finally is discharged from the upper drainage duct 2. Continuous water delivery can stably take away the heat of the center of the large volume concrete. Effectively cool the high-temperature parts such as the center of the large volume concrete.

[0034] The first heat conducting rod 3 on the outer wall of the main cooling pipe 1 is arranged in a cross shape, which effectively conducts the heat of the concrete around the main cooling pipe 1 to the main cooling pipe 1, and then the heat is taken away by the water flow, effectively cooling a large area of ​​the central part of the concrete.

[0035] After the concrete is cooled, cement slurry is used to penetrate and fill the interior of the main cooling pipe 1 and the drainage pipe 2. The combination of the main cooling pipe 1, the drainage pipe 2 and the concrete also has the function of increasing the concrete structure. Specific embodiment 2:

[0037] Based on the specific embodiment 1, the difference of this embodiment is that:

[0038] like Figure 3-4 As shown, the outer wall of the main cooling pipe 1 is fixedly connected to a plurality of branch drainage pipes 9. A row of second water stop plates 10 evenly distributed along the axial direction are fixed to the outer wall of the branch drainage pipe 9. A second rectangular plate 11 is fixed to the outer wall of the end of the branch drainage pipe 9. Four second steel bar heads 12 are fixed to the side of the second rectangular plate 11 away from the end face of the branch drainage pipe 9. The distance between the second rectangular plate 11 and the end face of the branch drainage pipe 9 is not more than 18 mm. A second internal thread 13 is provided on the inner wall of the end of the branch drainage pipe 9. Among them, the end of the branch drainage pipe 9 is threadedly connected with a second bolt 16.

[0039] In order to avoid the reduction of the cooling capacity of the rear section caused by the main cooling pipe 1 being too long, the ends of the multi-section branch drainage pipes 9 installed on the main cooling pipe 1 can be connected to the above-mentioned water pipe joints 8, and the water pipe joints 8 are connected to the water supply pipe to increase the effective cooling of the upper half of the main cooling pipe 1 and further improve the cooling effect. Specific embodiment three:

[0041] Based on the specific embodiment 1, the difference of this embodiment is that:

[0042] like Figure 5 As shown, a plurality of second heat-conducting rods 14 arranged perpendicular to the axial direction are fixed to the outer wall of the drainage conduit 2. When the cooling device is used for large-volume concrete that is difficult to cool to the side and can only be cooled upward, the main cooling pipe 1 is arranged horizontally, the upper ends of the two drainage conduits 2 extend out of the concrete, and the second heat-conducting rods 14 are arranged on the drainage conduits 2 to form a U-shaped large-scale cooling section, and then water is passed to cool the concrete, thereby improving the cooling efficiency of large-volume concrete.
